Stannane


Stannane or tin hydride is an inorganic compound with the chemical formula SnH4. It is a colourless gas that ignites on contact with air. SnH4 is a heavy analogue of methane but much less robust. In contrast to this rarely used species, stannane also refers to a large collection of organotin compounds.

Preparation and reactions

Stannane can be prepared by the reaction of tin chloride| and lithium aluminium hydride according to the following idealized equation:
Stannane decomposes slowly at room temperature to give metallic tin and hydrogen.
Organotin hydrides are more stable, e.g. triphenyltin hydride, also known as triphenylstannane.

Occurrence in industry

The volatility of stannane is potentially relevant to production of microchips.
